Aim: This study aimed to assess the effect of two resilient attachments used for retention of mandibular over-denture supported by an implant and a natural tooth on the supporting structures throughout a one-year follow-up period. Materials and methods: Fourteen patients with maxillary completely edentulous arches and only one standing natural mandibular canine were selected. Each patient received a dental implant with 10.5 mm length and 3.8 mm diameter at the canine region of the contralateral side of the mandible. The patients were divided into two groups according to the type of attachment used (n=7); BC group included patients who received mandibular over-dentures retained by bar clip attachment supported by an implant on one side and a natural tooth on the other side. BS group involved patients who received a mandibular implant splinted to the natural canine by bar joint attachment utilizing soft liner material. The patients of both groups were rehabilitated with conventional maxillary complete dentures. Clinical and radiographic assessment were performed immediately after over-denture delivery, six and twelve months from denture insertion. Clinical evaluation involved gingival index. Radiographic evaluation included measuring mesial, distal, buccal and lingual bone height differences. Results: BC group recorded significantly higher bone loss compared to BS group around both dental implants and natural teeth. Conclusion: Considering the limitations of this study, it could be concluded that soft liner retained over-dentures are more effective in decreasing bone resorption around the implants and natural teeth compared to clip retained over-dentures.

Resumo O objetivo deste artigo é apreender os desafios nas vivências dos usuários e profissionais de Banco de Leite Humano no atendimento a homens transgêneros no contexto da amamentação sob à luz da Interseccionalidade. Estudo qualitativo descritivo-exploratório a partir de entrevistas realizadas com seis profissionais do Banco de Leite Humano, que atenderam previamente homens trans no contexto de amamentação, e dois homens trans bissexuais, que amamentaram ao peito. Os dados foram tratados pela Análise Temática com auxílio do software Atlas.ti versão 9.0. Observam-se lacunas nas esferas educacionais, institucionais e na gestão, associadas a questões pessoais e sociais, que reproduzem um modelo pré-concebido normativo, desconsiderando as singularidades requeridas no atendimento à população trans no contexto da amamentação. A cisheteronormatividade e a supremacia do profissional operam em âmbitos pessoais, sociais e institucionais para a segregação de homens transgêneros nos serviços de suporte à amamentação. A análise interseccional destes desafios permite uma visão global dos fatores de segregação e a implementação de políticas públicas promotoras da justiça social.
Abstract This article tried, from an intersectional standpoint, to grasp the challenges experienced by health professionals and service users of human milk banks in provision of care for transgender men chestfeeding. This exploratory, descriptive qualitative study drew on interviews of six human milk bank staff, who had previously assisted trans men in relation to chestfeeding and two bisexual trans men, who chestfed. The data was treated by thematic analysis, supported by Atlas.ti software, version 9.0. Lacunas in the educational, institutional and management spheres, associated with personal and social issues, reproduce a pre-conceived normative model and disregard the special demands of providing chestfeeding care for the trans population. Cisheteronormativity and "professional supremacy" operate in personal, social and institutional respects to segregate transgender men in lactation support services. Intersectional analysis of these challenges affords an overall view of segregative factors and enables public policies to be introduced to promote social justice.

Objective@#To present a case of transorbital penetrating intracranial injury successfully managed using a stepwise multispecialty approach.@*Methods@#This is a case report.@*Results@#A 26-year-old male presented with a motorcycle side-mirror metal bar impaled into his right orbit. He had a Glasgow Coma Scale (GCS) score of 12. Computed tomography (CT) imaging revealed the metal bar’s trajectory from the right lateral canthus, traversing the superior orbital wall and frontal lobe, resulting in contusion, intracranial hemorrhages and multiple orbital and facial fractures. Despite the severity of the injury, the right globe was found to be intact during intraoperative exploration. The transorbital approach was employed for safe removal of the penetrating object, followed by repair of full-thickness eyelid laceration and transections of the lateral and medial canthi. Subsequently, the Neurosurgery service conducted a right pterional craniotomy, debridement, and duraplasty. Upon discharge, the visual acuity on the right eye was 20/50.@*Conclusion@#Transorbital penetrating intracranial injuries are rare and result in vision loss and life-threatening complications. A transorbital approach in removing a penetrating foreign body can be adopted when injury to cerebral tissues is imminent. Individualizing the management and employing a multispecialty approach can lead to favorable outcomes.

Pelvi-ureteric junction obstruction (PUJO) is not a rare clinical entity. It is indeed one of the common urological conditions presenting most commonly with hydronephrosis and pain. The most common etiology for patients suffering from acquired PUJO is the presence of calculus/calculi. An aberrant renal vessel (now termed as a vascular bar) is one of the causes in adults which are often missed on pre-operative investigations and is detected intraoperatively. We present herein the case of a 28 years old female who came with complaints of loin pain for 2 – 3 months. The workup investigations revealed only hydronephrosis without any calculi. Thus, a diagnosis of the primary PUJO was made. The patient was successfully managed by a laparoscopic pyeloplasty.

Urinary bladder neoplasm is the 10 most common cancer in the world, predominantly affecting males. Nowadays incidence of urinary bladder carcinoma in female has increased. It is a uncommon type carcinoma of urinary bladder. It resembles to non-keratinizing carcinoma of nasopharynx. This study report a case of 65 years old male presented with painless gross hematuria for 3 weeks. Patient was a known case of Meckel's diverticulum. Ultrasonography and cystoscopy showed a mass on lateral wall of urinary bladder measuring 3x3 cm . A radical cystectomy of the urinary bladder tumor was done. He was diagnosed as case of lymphoepithelioma like carcinoma of urinary bladder along with benign prostate hyperplasia and Meckel's diverticulum was made with stage 2. According to the WHO classification criteria, Lymphoepithelioma like carcinoma is a subtype of undifferentiated carcinomas. Immunohistochemical stains are helpful to differentiate Lymphoepithelioma from primary lymphoma of the bladder. Differentiation of LELCB from urothelial carcinoma is important, since it has better prognosis compared to pure urothelial carcinoma. It is important to diagnose this neoplasm for therapeutic as well as prognostic purpose.

Scaffold hopping refers to computer-aided screening for active compounds with different structures against the same receptor to enrich privileged scaffolds, which is a topic of high interest in organic and medicinal chemistry. However, most approaches cannot efficiently predict the potency level of candidates after scaffold hopping. Herein, we identified potent PDE5 inhibitors with a novel scaffold via a free energy perturbation (FEP)-guided scaffold-hopping strategy, and FEP shows great advantages to precisely predict the theoretical binding potencies ΔG FEP between ligands and their target, which were more consistent with the experimental binding potencies ΔG EXP (the mean absolute deviations | Δ G FEP - Δ G EXP | < 2 kcal/mol) than those ΔG MM-PBSA or ΔG MM-GBSA predicted by the MM-PBSA or MM-GBSA method. Lead L12 had an IC50 of 8.7 nmol/L and exhibited a different binding pattern in its crystal structure with PDE5 from the famous starting drug tadalafil. Our work provides the first report via the FEP-guided scaffold hopping strategy for potent inhibitor discovery with a novel scaffold, implying that it will have a variety of future applications in rational molecular design and drug discovery.

Objective To study dynamic compression performance of adipose tissues, so as to further reveal the damage mechanism, and provide references for medical treatment.Methods Based on the improved split Hopkinson pressure bar (SHPB) experimental device, the adipose tissue dynamic compression experiment was conducted. The stress-strain curves of adipose tissues at different strain rates were obtained. Then the numerical model of SHPB was established, and the experimental process was simulated and analyzed. The numerical simulation for penetration process of 32 mm diameter rubber non-lethal projectile into the simulated target in human abdomen was carried out.Results Adipose tissues had a noticeable strain rate effect. The stress-strain curves at two high strain rates were approximately straight lines. The slope was similar, and the elastic modulus was 3.25 MPa, which was about 6 times of that under a quasi-static state. The simulation curves of fat SHPB were consistent with the experimental curves, which verified correctness of the constitutive model. In the process of non-lethal projectile penetrating human abdomen, an annular convex area similar to water wave appeared on skin surface, and the fat layer absorbed about 67% of the impact kinetic energy.Conclusions The experimental data of adipose tissues are very accurate. Numerical simulation can reproduce the penetration process well, and provide references for studying the damaging effect of non-lethal weapons on human body.

In this study,a fluorescent(FL)aptasensor was developed for on-site detection of live Salmonella typhimurium(S.T.)and Vibrio parahaemolyticus(V.P.).Complementary DNA(cDNA)of aptamer(Apt)-functionalized multicolor polyhedral oligomeric silsesquioxane-perovskite quantum dots(cDNA-POSS-PQDs)were used as encoded probes and combined with dual-stirring-bar-assisted signal amplification for pathogen quantification.In this system,bar 1 was labeled with the S.T.and V.P.Apts,and then bar 2 was functionalized with cDNA-POSS-PQDs.When S.T.and V.P.were introduced,pathogen-Apt complexes would form and be released into the supernatant from bar 1.Under agitation,the two complexes reached bar 2 and subsequently reacted with cDNA-POSS-PQDs,which were immobilized on MXene.Then,the encoded probes would be detached from bar 2 to generate FL signals in the supernatant.Notably,the pathogens can resume their free state and initiate next cycle.They swim between the two bars,and the FL signals can be gradually enhanced to maximum after several cycles.The FL signals from released encoded probes can be used to detect the analytes.In particular,live pathogens can be distinguished from dead ones by using an assay.The detection limits and linear range for S.T.and V.P.were 30 and 10 CFU/mL and 102-106 CFU/mL,respectively.Therefore,this assay has broad application potential for simultaneous on-site detection of various live pathogenic bacteria in water.

The treatment of trigeminal neuralgia (TN) consists of pharmacotherapy and neurosurgical procedure, such as percutaneous radiofrequency rhizotomy. Here, we present the case of a patient with TN refractory to clinical treatment who presented an anatomical variation in the oval foramen, which required stereotactic-guided surgery to access the Gasser ganglion. This is a 63-year-old male patient who presented with TN refractory to drug treatment. He used carbamazepine and nortriptyline, with no satisfactory response. The percutaneous approach to radiofrequency thermocoagulation was indicated, in view of the comorbidities presented and the patient's age. Due to the presence of a rare anatomical variation, stereotactic-guided surgery was used to cannulate the foramen ovale and, thus, successfully perform the neurosurgical procedure with an excellent clinical response. The use of stereotaxy to guide cannulation of the foramen ovale due to anatomical variation was essential for the success of the procedure. The knowledge of the existence of this anatomical variation, and the mastery of the stereotactic technique enabled the adequate management in the face of the unusual situation.
O tratamento da neuralgia do trigêmeo (NT) consta de farmacoterapia e procedimento neurocirúrgicos, como a rizotomia percutânea por radiofrequência. Aqui apresentamos o caso de um paciente com NT refratária ao tratamento clínico que apresentava uma variação anatômica no forame oval, o que exigiu a realização de cirurgia guiada por estereotaxia para acesso ao gânglio de Gasser. Trata-se de um paciente do sexo masculino, com 63 anos de idade, que apresentava quadro de NT refratária ao tratamento medicamentoso. Fez uso de carbamazepina e nortriptilina, sem resposta satisfatória. Foi indicada a abordagem percutânea para termocoagulacão por radiofrequência, tendo em vista comorbidades apresentadas e a idade do paciente. Devido à presença de uma rara variação anatômica, utilizou-se a cirurgia guiada por estereotaxia para canular o forame oval, e, dessa forma, realizar o procedimento neurocirúrgico com sucesso e uma excelente resposta clínica. A utilização de estereotaxia para guiar a canulação do forame oval devido à variação anatômica foi essencial para o sucesso do procedimento. O conhecimento da existência dessa variação anatômica, e o domínio da técnica estereotáxica possibilitaram o adequado manejo frente a uma situação incomum.

Objective:To investigate the effects of Flexi-bar on nonspecific low back pain. Methods:From June, 2020 to January, 2021, 30 patients with nonspecific low back pain were enrolled. Firstly, all the patients performed core stabilization exercise (supine bridge, curl-up and four-point support) using Flexi-bar or not, respectively. And the difference of electromyography (EMG) root mean square (RMS) value of transversus abdominis and multifidus was observed. Secondly, they were randomly divided into control group (n = 15) and experimental group (n = 15). The control group performed core stabilization exercise, and the experimental group received Flexi-bar training in addition, 30 minutes a time, three times a week, for six weeks. They were evaluated with Visual Analogue Scale (VAS) and Oswestry Disability Index (ODI), and measured the thickness of transversus abdominis and the area of multifidus before and after training. Results:Firstly, there was significant difference in RMS of transversus abdominis and multifidus between using Flexi-bar or not (|t| > 2.468, P < 0.05), except the RMS of transversus in supine bridge (|t| < 2.029, P > 0.05). Secondly, before training, there was no significant difference between the control group and the experimental group (|t| < 1.944, P > 0.05); after training, the scores of VAS and ODI significantly decreased (|t| > 6.808, P < 0.001), the thickness of transversus abdominis and the area of multifidus significantly increased (|t| > 5.937, P < 0.001), and all the indexes were better in the experimental group than in the control group (|t| > 2.411, P < 0.05)， except the thickness of transverse abdominis (t = -1.431, P > 0.05). Conclusion:Flexi-bar could facilitate to reduce pain and improve the function of patients with nonspecific low back pain.

Abstract There has been a heated debate on emotional intelligence (EI) and, more particularly, on the Bar-On Emotional Quotient Inventory (EQ-i) measuring all dimensions of emotional intelligence. To ensure measurement equivalence of EQ-i, the present article evaluated whether statements phrased in EQ-i questionnaire have equivalent meaning across respondents, regardless of their sex and age group membership. For 2,078 participants, three EI subscale (item 50 in reality testing, items 4 and 19 in stress tolerance, and items 7, 52, and 82 in interpersonal) for age groups had clinically significant Differential item functioning (DIF). So previous observed associations between EI and age might be misleading and deserve further study after removing or replacing DIF items.
Resumen En medio del acalorado debate sobre la Inteligencia Emocional, este estudio retoma el Inventario de Cociente Emocional Bar-On (EQ-i), que mide todas las dimensiones de este constructo psicológico. Con el fin de comprobar la equivalencia de medición de EQ-i, se comprueba si las declaraciones formuladas en el cuestionario EQ-i tienen un significado equivalente entre los encuestados, independientemente de su sexo y grupo de edad. Se aplicó a los 2078 participantes las tres subescalas de IE. Se halló un funcionamiento diferencial de los ítems (DIF) clínicamente significativo. Por lo tanto, las asociaciones observadas anteriormente entre la IE y la edad pueden ser espurias y merecen un estudio adicional después de eliminar o reemplazar los elementos DIF.

Abstract Objective: This study investigated stress and performance levels in candidates for the Brazilian Bar Association examination (Exame da Ordem dos Advogados do Brasil) in Rio Grande do Sul, Southern Brazil. Methods: The following instruments were used: A sociodemographic data sheet, Lipp's Stress Symptom Inventory for Adults, the Ways of Coping Scale, the Adult Self-Report Scale, and the Self-Report Questionnaire. The final sample comprised 117 candidates, aged from 18 to 59 years (mean = 29.7, standard deviation = 7.8), 76 women (65%) and 41 men (35%). Results: In the first phase of the examination, 67 candidates were approved (57.3%), but there was no significant difference in terms of stress: stress symptoms were present in 76.1% of the successful candidates and 62% of the unsuccessful candidates; (χ2 (1) = 2.09; p = 0.148). In terms of stress phases, 70.6% of the successful candidates (n = 36) were in the resistance phase and 78.4% of these had psychological symptoms. The mean age of successful candidates (28.2 years) was lower than that of unsuccessful candidates (31.7 years); (t (115) = −2.48; p = 0.015). Attention deficit/hyperactivity disorder symptoms were detected in 18 successful candidates (26.9%) and 6 unsuccessful candidates (12.2%); (χ2 (1) = 2.85; p = 0.091). Conclusions: Candidates who were successful in the first phase of the Brazilian Bar Association examination tended to be younger and scored higher for attention deficit/hyperactivity disorder symptoms, but their stress levels did not differ from those of unsuccessful candidates.
